Member Function Documentation

template<class T >

gear::Vector3D::operator T ( )

inline

Implicit templated conversion to anything that has a c'tor T(x,y,z) and accessor functions x(),y(),z().

For safety the result is checked which causes a small performance penalty.

to()

template<class T >

T gear::Vector3D::to ( )

inline

Explicit, unchecked conversion to anything that has a c'tor T(x,y,z).

Example: CLHEP::Vector3D clhv = v.to< CLHEP::Vector3D>() ;
